Abstract

A host and a storage system communicate with each other by using a NVMeoF protocol are provided. In some embodiments, the host accesses a logical disk of the host by using a control node in the storage system, and sends a state query command to the control node. The state query command is configured to instruct the control node to report a path state of a path corresponding to the control node. Still in those embodiments, the host receives the path state reported by the control node. When the received path state indicates that the logical disk includes an access interval, the host sends an interval query command to the control node; receives access interval information reported by the control node; and records a mapping relationship between the control node and the access interval information.
